When credibility attacks: The reverse impact of source credibility on persuasion

Recent research on the self-validation hypothesis suggests that source credibility identified after message processing can influence the confidence people have in their own thoughts generated in response to persuasive messages (Briñol, Petty, & Tormala, 2004). The present research explored the implications of this effect for the possibility that high credibility sources can be associated with more or less persuasion than low credibility sources. In two experiments, it is demonstrated that when people generate primarily positive thoughts in response to a message (e.g., because the message contains strong arguments) and then learn of the source, high source credibility leads to more favorable attitudes than does low source credibility. When people have primarily negative thoughts in response to a message (e.g., because it contains weak arguments), however, this effect is reversed—that is, high source credibility leads to less favorable attitudes than does low source credibility.     

Cheap talk and credibility: The consequences of confidence and accuracy on advisor credibility and persuasiveness

Is it possible to increase one’s influence simply by behaving more confidently? Prior research presents two competing hypotheses: (1) the confidence heuristic holds that more confidence increases credibility, and (2) the calibration hypothesis asserts that overconfidence will backfire when others find out. Study 1 reveals that, consistent with the calibration hypothesis, while accurate advisors benefit from displaying confidence, confident but inaccurate advisors receive low credibility ratings. However, Study 2 shows that when feedback on advisor accuracy is unavailable or costly, confident advisors hold sway regardless of accuracy. People also made less effort to determine the accuracy of confident advisors; interest in buying advisor performance data decreased as the advisor’s confidence went up. These results add to our understanding of how advisor confidence, accuracy, and calibration influence others.     

The discovery of pluralistic ignorance: An ironic lesson

In recent years, an increasing number of social and behavioral scientists have begun to pay serious attention to pluralistic ignorance, the shared false ideas of individuals about the sentiments, thoughts, and actions of others. Most of these researchers are unaware of the original effort to investigate these patterns of cognitive error and, consequently, misunderstand, as did the original investigators, some of the implications of their own work. The discovery of this important social phenomenon by Floyd H. Allport and his students, Daniel Katz and Richard L. Schanck, and how their preoccupation with individual characteristics and their relative neglect of social characteristics led them to underestimate the value of their discovery, is discussed. Allport's original interest in pluralistic ignorance and how he and Katz documented it empirically are presented, as is a review of Schanck's research extending their analysis.     

Proactive Personality and Employee Creativity: The Effects of Job Creativity Requirement and Supervisor Support for Creativity

This study examined the relationships between proactive personality and employee creativity and the moderating roles of job creativity requirement and supervisor support for creativity in activating proactive personality associated with employee creativity. To provide a rigorous test of the hypotheses, we conducted a field study from a sample of 157 employee–supervisor pairs in South Korea. The results revealed that a proactive personality was positively associated with employee creativity. In addition, job creativity requirement and supervisor support for creativity jointly influenced the relationship between proactive personality and employee creativity. Specifically, proactive employees exhibited the highest employee creativity when job creativity requirement and supervisor support for creativity were both high.     

Creativity through Connectedness: The Role of Closeness and Perspective Taking in Group Creativity

Achievements in various fields of creativity are resulting more and more from collaborative teams. This research investigated the role of interpersonal process variables, namely closeness and perspective taking in group creativity, with a 2 by 2 experimental design. Sixty-one 3-person groups assigned to 4 conditions (a: closeness and perspective taking, b: perspective taking, c: no closeness and no perspective taking, d: closeness). Group members collaboratively wrote stories that were rated by 3 independent expert judges. There was a positive main effect of closeness and negative main effect of perspective taking on group creativity scores. Moreover, the significant interaction between perspective taking and closeness displayed that combination of closeness with perspective taking negatively affect group creativity. These results indicate that closeness might be beneficial for group creativity only when it is not accompanied with perspective taking.     

Personality and Creativity: The Dual Pathway to Creativity Model and a Research Agenda

To better understand the relation between personality traits and creativity, we invoke the Dual‐Pathway to Creativity model (DPCM) that identifies two pathways to creative outcomes: (1) flexible processing of information (cognitive flexibility) and (2) persistent probing, and systematically and incrementally combining elements and possibilities (cognitive persistence). DPCM further proposes that dispositional or situational variables may influence creativity through either their effects on flexibility or persistence. Here, we propose the idea that approach‐related traits (e.g., openness to experience, extraversion, positive affectivity, and power‐motivation) may lead to greater creativity because they link to enhanced cognitive flexibility, whereas avoidance‐related traits (e.g., negative affectivity and neuroticism) under the right circumstances may lead to greater creativity because they link to enhanced cognitive persistence. Empirical support for this proposition is discussed, and a research agenda for future work on personality and creativity is set.     

The Notion of Creativity Revisited: A Philosophical Perspective on Creativity Research

This article is a critical, yet constructive, review of some recent attempts to define and understand creativity, informed by the methods and debates of contemporary philosophy. I argue that the definitional project is not essential to creativity research, but important nevertheless. The standard definition of creativity as the production of something that is both novel and appropriate is on the right track, but needs further qualification and tends to be elaborated in ways that make it either too narrow or too broad. I argue that the product, and not the person or process, should be viewed as the primary bearer of creativity and criticize some influential theorists for making creativity too strongly dependent on social acceptance, while also recognizing that the realist alternative tends to widen, and thus threatens to trivialize, the central notion of an appropriate product. The notion of response‐dependence might be of some help to find the proper balance between the two extremes, and some comparisons with evolutionary theory also help to shed further light on the problem. Finally, I try to spell out the practical consequences of my investigation for creativity research.     

Creativity in Context: The Ecology of Creativity Evaluations and Practices in an Artistic Craft

The present article reports a study on the use of a multiple feedback methodology for creativity evaluation in the case of Romanian Easter eggs. Four groups of evaluators —i.e. ethnographers, priests, art teachers and folk artists—all members of professional communities relevant for this particular folk art participated in the study. They almost unanimously appreciated ‘traditional’ wax decorated eggs as highly creative for their designs, aesthetics and the hard work and talent they require but opinions diverged when commenting on the creativity of other types of Easter eggs. At a more general level, two broad evaluation patters were found, corresponding to whether respondents participate or not in decoration practices. Identifying these patterns comes to reinforce the idea that creativity evaluations, as well as creative activity, are rooted in the social and cultural contexts of the participants and these contexts share important similarities but also marked differences.     

Beyond risk and ambiguity: Deciding under ignorance

In this study, we examined the neural basis of decision making under different types of uncertainty that involve missing information: ambiguity (vague probabilities) and sample space ignorance (SSI; unknown outcomes). fMRI revealed that these two different types of uncertainty recruit distinct neural substrates: Ambiguity recruits the left insula, whereas SSI recruits the anterior cingulate cortex, bilateral inferior parietal cortex, and the lateral orbitofrontal cortex. The finding of unique activations for different types of uncertainty may not necessarily be predicted within the reductive approach of modern theories of decision making under uncertainty, because these theories purport that humans reduce more complicated uncertain environments to subjectively formed less complicated ones (i.e., SSI to ambiguity). The predictions of the reductive view held only for ambiguityaverse individuals and not for ambiguity-tolerant individuals. Consequently, theories of decision making under uncertainty should include individual tolerance for missing information and how these individual differences modulate the neural systems engaged during decision making.

Narrowing the Creativity Gap: The Moderating Effects of Perceived Support for Creativity

This article examines the role of 3 types of perceived support for creativity in moderating the relation between creative self-efficacy and self-perceived creativity. The findings suggest significant interaction effects for perceived work-group support and supervisor support, but not for perceived organizational support. This study is among the first to (a) examine the importance of perceived support for creativity in unlocking creative potential and increasing creativity in organizations and (b) use interaction terms in structural equation modeling (SEM) to investigate moderator effects in an applied research setting. These results imply that organizational interventions focused on training supervisors and work-group members to support creativity in the workplace may be more effective than broader and less focused interventions at the organizational level.     

Assessing the impact of policy analysis: The functions of usable ignorance

Conclusion Policy analysis is a specialized intellectual activity that affects and is affected by the exercise of power, rule, and authority in knowledge systems. The organized complexity of this system, formed by the interpenetration of tangled knowledge functions which appear as a river delta, raises doubts about the appropriateness of policy impact as a standard of accountability for policy analysts. The typical practice of “random medition” may be replaced with forms of “systematic mediation” which, directed towards the investigation of rival hypotheses about the policy impact of policy analysis, enlarges the scope of usable ignorance. The strategy of usable ignorance, supplemented by recommendations in areas of agenda setting, managing pragmatic validity, and methodology development, is a way to begin dealing with the organized complexity of the knowledge system in which policy analysts work today.

The Measurement of Negative Creativity: Metrics and Relationships

Although the dark side of creativity and negative creativity are shaping into legitimate subconstructs, measures to assess the same remain to be validated. To meet this goal, two studies assessed the convergent, predictive, and criterion-related validities of two valence-inclusive creativity measures. One measure assessed the self-report endorsement of social creativity, and the other was an Alternate Uses Test (AUT) assessing generation of nonsocial creativity. Participants (N = 129, 88 women, M_age = 25.09 years, SD = 10.03) completed the two creativity measures and three Dark Triad personality scales (narcissism, psychopathy, Machiavellianism) through an online form. Correlations and multiple regressions were employed in the studies. Study 1 assessed the convergent and predictive validities between the two measures. Results indicated a strong convergence on the measurement of positive creativity, but not on negative creativity. Study 2 used the Dark Triad of personality as an external criterion to evaluate the criterion-related validity of the measurement of negative creativity. Although the Dark Triad predicted the self-reported endorsement of negative creativity, there was no discernable relationship with the generation of negative-creative responses on the AUT. Implications of current results, and suggestions for future metrics of valence-inclusive creativity are discussed.     

认知抑制对科学创造力和艺术创造力的影响

研究通过2个实验,考察不同高低抑制水平对科学创造力和艺术创造力的影响。通过安排不同难度的Simon任务（不一致试次占70%或10%）来消耗被试的认知资源,达到操纵被试的抑制水平,以侧抑制任务的前后测来评估被试抑制水平的变化情况,实验1和实验2分别以科学创造力测验和粘贴画任务测量被试的科学创造力和艺术创造力。结果发现,在科学创造力测验上,高抑制水平组被试的流畅性和灵活性得分显著高于低抑制水平组;在粘贴画任务中,低抑制水平组被试的创造性、可爱程度、综合印象得分以及总分均显著高于高抑制水平组。表明高认知抑制水平有利于科学创造力,低认知抑制水平有利于艺术创造力,认知抑制对科学创造力和艺术创造力的影响存在分离效应。
